Jübergturm

In the heart of Sauerland, amidst the picturesque landscape of Hemer, stands an architectural marvel that beckons both locals and tourists alike. The Jübergturm, a 23.5-meter-high observation tower, is not just a structure but a symbol of modern ingenuity intertwined with natural beauty. It was constructed for the 2010 Landesgartenschau (State Garden Show) and has since become a beloved landmark within the Sauerlandpark Hemer.

The History of Jübergturm

The journey of Jübergturm began with an ambitious vision to create a unique observation tower for the Landesgartenschau Hemer 2010. Initially, plans proposed a predominantly steel and concrete structure with broad staircases, designed by Swiss architects Beat Müller and Katharina Schewe. However, environmental concerns led to the rejection of this design. The project then shifted focus towards a more sustainable material – wood.

After a series of public protests and consultations, the citizens of Hemer were invited to vote on the design. The winning design, albeit smaller and modified, was still the work of Müller and Schewe but now envisioned as a wooden staircase structure. Despite this, due to financial constraints, the second-place design by Stuttgart architects Birk and Heilmeyer, in collaboration with the engineering firm Knippers Helbig, was ultimately realized. This design drew inspiration from the hyperbolic lattice shell structures of Russian engineer Vladimir Grigorievich Shukhov.

The construction of the tower was generously supported by the foundation of the Stadtsparkasse Hemer, with a contribution of approximately 450,000 euros. After months of meticulous work, including night shifts in the final weeks, the tower was completed and officially opened to the public on April 16, 2010, just in time for the Landesgartenschau. The official handover to the citizens of Hemer took place on September 5, 2010, marking a significant moment in the town’s history.

The Unique Construction of Jübergturm

The Jübergturm is a testament to innovative engineering and design. Standing on a base at an elevation of 293.7 meters, the tower itself reaches a height of 23.5 meters. Its construction employs the Shukhov principle of hyperbolic lattice shells, adapted uniquely to wood. According to the architects, it is the first true wooden hyperboloid structure, where only the external lattice bears the load.

The tower’s exterior is composed of two levels of interlocking wooden beams, totaling 240 straight timbers. These beams, each with a cross-section of 8 cm by 8 cm, are arranged in opposing diagonal patterns, creating a visually striking and structurally sound framework. The beams vary in length, with each set of six beams ending at different heights, contributing to the tower’s tapering silhouette.

Inside the tower, five flights of stairs with a total of 125 steps lead visitors to the top platform. The number of beams decreases with each ascending platform, giving the tower an increasingly open feel as one climbs higher. The five observation platforms are situated at heights of 4.38 meters, 8.75 meters, 13.13 meters, 17.50 meters, and 21.88 meters, respectively.

Panoramic Views and Visitor Experience

Ascending the Jübergturm is a journey that rewards visitors with breathtaking panoramic views of the surrounding Sauerland region. From the highest platform, at an elevation of 315.62 meters, one can gaze out over the town of Hemer, the former Blücher-Kaserne, and the expansive eastern plateau of the Sauerlandpark Hemer. The view is particularly enchanting at sunrise or sunset, when the landscape is bathed in golden light.

For those who prefer a more leisurely approach, the tower is accessible via the Himmelsleiter (Heaven’s Ladder) staircase and a barrier-free zigzag path that begins in the town center and winds through the former Blücher Barracks grounds. This ensures that everyone, regardless of mobility, can enjoy the splendor of the Jübergturm.

Conclusion

The Jübergturm is more than just an observation tower; it is a symbol of community spirit, innovative design, and harmonious integration with nature. Its unique wooden structure, inspired by historical engineering principles, stands as a testament to modern architectural prowess. Whether you're a history enthusiast, a nature lover, or simply in search of a spectacular view, a visit to the Jübergturm in Hemer is an experience not to be missed. As you stand atop this remarkable tower, taking in the sweeping vistas of the Sauerland, you'll understand why the Jübergturm has become a cherished landmark and a source of pride for the people of Hemer.
